Hello, I am hoping someone can help me figure out my current issues with a new laser. I have the A40 Pro V2 with extension kit. Since unboxing and building I have been unable to get the machine to start a project. It will sometimes frame a project but will not home properly either. When homing it does not respond at all. After framing a project and pressing start I am getting Alarm Code 1: Hard limit-rehome. The machine will not rehome after that code. I am attaching photos and screenshots of my specific setup and screenshots of what I think is relevant software settings. Any help would be much appreciated as Atomstack customer service has been essentially unhelpful.
Home, Jog direction, and work coordinates have to be set up in that order. I do not see anything in your settings that look incorrect.
Home: Once Lightburn sends the Home command to the laser, it is out of the picture until the Home cycle is complete. Lightburn sends the $H command.
In the Console window, enter $H and see if the laser does the Home dance.
Let us know if that works.
Thank youbfor your response. Oddly enough as i was checking some power feeds last night it began to work properly when the z axis was disabled manually (unplugged). Im assuming there is a problem with the z axis set up.
You unplug the Zaxis motor and Homing works? That is strange. Normally, the Zaxis must home first before X&Y will move. Yeah, I would agree with your diagnosis.
It is super strange and I have never seen that happen before. Like you said, the z axis does home first. This tells me that the homing alarm I was getting is coming from a problem with that axis. This particular machine has seperate “plug ins” for the laser and the zaxis though and since I mostly just cut material its not a huge deal right now. I do plan to track the problem down though at some point. Again, thank you for your help.

If I remember right, the Zaxis will move up fast until it hits a limit. Then it will drop slowly until it pulls of the switch. The $27 parameter has to be enough travel that the switch actually opens. 3mm is usually enough.
Once the switch opens, it will reverse and look for the switch to close again. Then a final pull off and Zhome is established. Then it goes on to the other guys.
